In Solaris 10, if you want to find the processor type and the number of physical processors installed on the system and the number of Virtual Processors available on the system then the psrinfo command does job for you.

In multiprocessor environments, Sun Solaris can allow enabling or disabling Processors. This although is not something that we would do all the time but can come handy when troubleshooting hardware issues.

Sun Solaris has the psradm utility which allows enabling or disabling a Processor on the system. The psradm utility changes the operational status of processors. The legal states for the processor are on-line, offline, spare, Faulted, and no-intr. An online processor processes LWPs (lightweight processes) and can be interrupted by I/O devices in the system.

Sun solaris has various different utilities to find the processor information on your hardware. Let’s have a look at the different utilities that can display the processor informations and the way they display information.
